Description

TECHNICAL FIELD

The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner constructed in such a manner that an extension tube, to which a suction portion is mounted at an end thereof, can be fixed to a cleaner body in a coupling state.

BACKGROUND ART

The vacuum cleaner is constructed to include a body in which a suction device such as a motor is installed, a connecting hose which is detachable from the body, and an extension tube which is connected to an end of the connecting hose. Further, a suction portion is mounted to an end of the extension tube. Suction support appliance is defined to include an extension tube and a suction portion.

In general, such suction support appliance is mounted to the cleaner body while it is not used. Further, in a conventional cleaner, the extension tube is generally mounted and fixed to a front or lateral face of the cleaner body when the tube is mounted to the cleaner body.

On the other hand, in a vacuum cleaner constructed in such a manner that a dust collector is mounted detachably to a rear face of the cleaner body, it is an important point where to mount the suction support appliance while the cleaner is not used. Further, it is very inconvenient to place or store the cleaner in such a state that the rear face of the cleaner body faces toward a bottom floor as in the conventional cleaner, since the dust collector exists in the rear face of the cleaner body. Therefore, the cleaner is usually stored in a state of general use. In such a case, it is not easy to properly mount the suction support appliance to the cleaner body.

SUMMARY OF INVENTION

The object of the present invention is to provide a vacuum cleaner having a constitution that a dust collector can be detachably mounted to a rear end of the cleaner and a suction support appliance can be more conveniently inserted and fixed to a cleaner body.

The vacuum cleaner of the present invention for achieving the above object comprises a cleaner body with a suction means installed therein; a dust collector mounted detachably in the rear of the cleaner body; and a suction support appliance for guiding air, introduced by the suction means, into the cleaner. Further, the suction support appliance is formed with a projecting hook portion, and a hook retention portion for engaging the projecting hook portion therewith is formed in the dust collector, whereby the suction support appliance can be hung on the dust collector.

According to an embodiment of the present invention, the hook retention portion of the dust collector is formed at a handle that is prominently formed at a rear face of the dust collector.

According to another embodiment of the present invention, the hook retention portion includes a groove that is opened upward, and the projecting hook portion includes an insert that is inserted into the groove.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Hereinafter, preferred embodiments of the present invention will be explained in detail with reference to the drawings.

As shown in FIG. 1, a vacuum cleaner according to the present invention is constructed to include a cleaner body 10, a dust collector 20 mounted detachable to a rear portion of the cleaner body 10, and a suction support appliance 50 having a constitution which is detachably mounted to the dust collector 20. A suction support appliance or device 50 includes an extension tube 30 and a suction portion 40.

A suction device, such as a motor and so forth, for generating a suction force is installed within the cleaner body 10, and the vacuum cleaner can generate the suction force. Further, the dust collector 20 is used for filtering dust from dust-containing air introduced by the suction force of the vacuum cleaner. The dust collector 20 primarily has a function of collecting the dust in accordance with a cyclonic method, and secondarily includes a dust-collecting filter for filtering fine dust. Further, a handle 22, by which a user grips the dust collector 20 during its insertion or removal, is formed in the rear of the dust collector 20.

In the present invention, it is a main technical feature that the suction support appliance 50 is constructed to be detachably mounted to the dust collector 20.

In addition, FIG. 2 shows an embodiment of the present invention wherein the handle 22 of the dust collector 20 is formed with a hook retention portion 24 for engaging a projecting hook portion 32 of the extension tube 30 therewith. That is, the handle 22 of the dust collector 20 is formed with an upwardly opened groove 24a and a slot 24b that is slit in the rear of the groove 24a along the longitudinal direction. As an embodiment for the substantial formation of the hook retention portion 24 according to the present invention, the above constitution having the groove 24a and the slot 24b is described herein.

Further, the projecting hook portion 32, by which the suction support appliance 50 is hung on the cleaner body 10 by inserting the projecting hook portion into the hook retention portion 24, is formed in suction support appliance 50 includes an extension tube 30 and a suction portion 40. The projecting hook portion 32 is constructed to have a T-shaped horizontal cross section, and comprises an insert 32a that is inserted into the upwardly opened groove 24 and a relatively narrow connecting portion 32b for connecting the insert 32a with the suction support appliance 50.

Therefore, the projecting hook portion 32 of the suction support appliance 50 can be hooked into the hook retention portion 24 formed in the handle 22 of the dust collector 20. Consequently, the suction support appliance 50 can be mounted to the cleaner body as a whole, and thus the condition as such can be maintained.

Considering a process of inserting the projecting hook portion 32 into the hook retention portion 24, the insert 32a of the projecting hook portion 32 is inserted downwardly from above into the upwardly opened groove 24a. At this time, the connecting portion 32b in the rear of the insert 32a is received in the slot 24b of the hook retention portion 24. Further, since a lower portion of the upwardly opened groove 24a is blind, the insert 32a can be received in the groove 24a and can be perfectly hooked therein.

It is needless to say that the projecting hook portion 32 and the hook retention portion 24 can be variously changed or modified. For example, it is most preferred that the projecting hook portion 32 be constructed to include the downwardly extending insert 32a, and that the hook retention portion 24 be constructed as the upwardly opened groove 24a. Of course, the other modifications or changes thereof can be made within the scope of the technical features as such.

Therefore, the cleaner according to the present invention can be conveniently stored merely by inserting the suction support appliance 50 of the cleaner into the dust collector 20 of the cleaner body 10.

According to the present invention constructed as such, the suction support appliance 50 connected to the suction portion of the vacuum cleaner can be very conveniently mounted to the dust collector of the cleaner body. Therefore, the extension tube can be most conveniently mounted on the cleaner wherein the dust collector is mounted in the rear of the cleaner body.

According to the present invention described above, it is a fundamental technical feature to construct the vacuum cleaner in such a manner that the suction support appliance 50 includes an extension tube and a suction portion can be hung on the dust collector. Although the present invention has been illustrated and described with reference to the preferred embodiment of the present invention, various changes, modifications and additions to the present invention will be apparent to those skilled in the art without departing from the spirit and scope of the present invention.
